Engine failure at 86370 miles while driving down the highway. Towed to Sullivan Tire, mechanic found 2 bad cylinders and the lifters had destroyed the cam, requiring a total engine replacement. This mechanical failure of the engine was sudden and unexpected, placing myself, my children, and other drivers at risk of injury on a very busy highway (MA-24). Discussing this with the mechanic (Sullivan Tire), this malfunction has been confirmed by a GMC certified dealer and service shop (McLaughlin Chevrolet) that there are several other Chevrolet/GMC vehicles that GMC technicians and third-party technicians that are reporting have had the same mechanical failure in the engine. I am unaware if this has been inspected by the manufacturer. It has only been inspected by third-party technicians at Sullivan Tire in Bridgewater, MA. There were no warning lamps, messages, or other symptoms of the problem prior to the failure.

The wiring harness of the vehicle was placed too close to the frame and began wearing the wires down until they broke. Once this happened, the vehicle turned off while driving and would not restart for a few minutes. The vehicle would turn off repeatedly every few minutes leaving me stranded in the middle of the street until I could get the truck to turn off and restart. There was no warning on when the engine would shut off, it just happened randomly while driving and while in park.

So my Silverado is having the same issues as many other Silverado owners. I originally had the vehicle in for service on a transmission issue, which is also another problem these vehicles are having. As for the engine issue I have experienced the vehicle stalling out after running rough, primarily after the vehicle has been running for a while. In addition, there are times when I am driving at highway speeds and the vehicle seems to shudder and shake. I thought OK maybe it's the wheel balance or alignment so I took it in for the wheel balance and the alignment and it still is doing the same thing. So at this point I had the spark plugs, wires and coil packs replaced. Still having the same issue. In addition to this I had the vehicle in for first time transmission hard shifting at around 20k miles. The technician took the vehicle for a drive and stated that there was an issue and that the computer reset should eliminate the problem. It didn't. So I dealt with this multiple times, bringing the vehicle to service for diagnosis and even filing a claim with GM. The vehicle is still experiencing these problems with the hard shifting. I had the recommended maintenance performed on the vehicle which included fluid replacement without a resolution to the issue. I have completely lost confidence in the GM products and their service technicians as they've been unable to repair the vehicle to proper running order. This will be my last GM product, and that says a lot coming from a GM family member. Sad that quality has significantly gone downhill.

In my 2019 Chevy Silverado, I experienced an oil leak in my garage. I have never had a leak since I purchased the new truck. I took it to the dealership, and they notified me that my engine oil cooler hose assembly was leaking and needed to be replaced. I asked if the truck was safe to drive and I was informed that it was. I was driving home from work when the warning chimes began, and a message on my screen said to pull over immediately due to a loss of oil pressure. I looked at my oil gauge which was already at zero. I pulled over as quickly and as safely as I could and shut off the engine. There was smoke coming from the engine compartment. I called my insurance and then a tow truck. The tow truck driver asked if this was a 2019 Silverado, I said yes, and he said that he has seen this before in other 2019 Silverado trucks. As well, the dealership also mentioned that they have seen this before.

While driving started making a ticking noise. Stopped the truck, to see if we could hear it again. Put truck in drive, check engine came one along with service park brake and esc warning lights; we were on a highway with minimal room to pull off. The truck started to shake at about 55 miles per hour. Made it home and took to Chevy dealer on Monday morning. Informed that the lifter went bad, in turn damaged the camshaft. After having the truck all week, total repairs topped out at $10,500. This is wrong especially when I searched internet and GM is well aware of this issue when no regards to safety of drivers.
